Project Update

April 3, 2024 - Northeastern Colorado - Videos highlight different aspects of the designs

Boulder - The Colorado Department of Transportation is sharing preliminary design recommendations to address transportation challenges along the Colorado Highway 7 (also known as Arapahoe Avenue) Multimodal Corridor from 28th Street and 63rd Street in Boulder.

A series of educational videos are available on the CDOT website that highlight examples of the proposed preliminary designs along CO 7 Multimodal Corridor Segment A. Shaped by community input from fall 2023 and past feedback. The videos offer a focused overview of specific areas along the corridor and show an example of the proposed multimodal improvements along CO 7 Segment A between 28th Street and 63rd Street.

“We’re very thankful for the feedback received so far. The comments about community needs, concerns, values, and areas of conflict helped refine the overall preliminary design and recommendations,” said CDOT Regional Transportation Director for Northeast Colorado Heather Paddock.

More about Segment A

The CO 7 Multimodal Corridor Segment A between 28th Street and 63rd Street is in the preliminary design study and environmental phase. The corridor is a critical commuter and business route (transit, biking, personal vehicle, goods movement) connecting the Northwest Region. The project area is commonly known as East Arapahoe, a six-lane road and one of Boulder's most heavily traveled commuter corridors. This project will provide a safe multimodal transportation system that supports the economy, enhances the environment and improves the quality of life for both residents and visitors.

As part of the preliminary design phase, the project team will identify infrastructure costs that help us pursue funding to construct the improvements in the future.
